Fuel gauge grow effect

This goes in the documents header:

<script src="RGraph.common.core.js"></script>
<script src="RGraph.fuel.js"></script>

Put this where you want the chart to show up:

<canvas id="cvs" width="600" height="250">
    [No canvas support]
</canvas>

This is the code that generates the chart:

<script>
    window.onload = function ()
    {
        var data = [4,8,6,3,1,2,5,8,9];

        var fuel = new RGraph.Fuel({
            id: 'cvs',
            min: 0,
            max: 100,
            value: 56,
            options: {
                textAccessible: true
            }
        }).grow();
        
        
        setTimeout(function ()
        {
            fuel.value = 12;
            fuel.grow();
        }, 3500);
    };
</script>
